Overmoulding involves moulding one plastic material on top of another to make a single part. From consumer products such as toothbrushes, to industrial power tools, automotive mounts / clamps, IP-rated electronic gadgets, and medical devices, overmoulded parts have myriad applications. Aesthetics, ergonomics, functionality, durability – overmoulding delivers many advantages that are not possible through regular moulding and assembly.
Greater flexibility with part design
Wide selection of materials, including tough thermoplastics like polycarbonate or nylon, as well as softer materials such as polystyrene and TPE
Enhanced ergonomics and functionality, with features such as soft grips and flexibility made possible through material combinations
Improved part strength and durability, alongside advantages such as shock resistance and vibration damping
Superior fit and alignment compared to assembled parts
Higher efficiency and faster time-to-market through manufacturing fewer steps
Lower cost owing to savings on assembly, labour, and other secondary operations
To achieve these advantages, overmoulding requires careful tool design and construction, as well as informed material choices. If you’re exploring how to achieve cost and operational efficiency through overmoulding, for a new or existing part, our team can help.
